What only a9 can do This mechanism-free camera can deliver a-class-above performance conventional mechanical SLRs have only sought. For example, this system realizes a totally blackout-free viewfinder while conventional systems can only try to reduce blackout time. A high-speed, vibration-free, silent Anti-Distortion shutter vastly extends the range of shooting situations while a mechanical system can only aim for lower vibration and quieter shutter release sound. a9 provides continuous tracking of moving subjects for foolproof AF/AE while traditional SLRs can only challenge such AF/AE performance improvements. Moreover, a9 allows its viewfinder to show not only images of the subject – available on conventional systems – but also the final image of a shot. Now, thanks to a new image sensor that superbly manages all these roles, you can surpass all expectations with a9. Note: This camera is equipped with electronic and mechanical shutters. The features described in this section are primarily related to electronic shutter operation.
